Meghan:
I've seen others with that stroller and there are plusses and minuses. THe plus is that you don't have to haul a car seat with you throughout the airport, etc. The minus is that the stroller then is a bit large to fit into a cruise ship cabin, since it's wide enough to be a car seat. We usually take a small fold up stroller (has an awning to keep the sun out, etc.) so that we can store it in the entrance way to our cabin. Sometimes we'll keep it folded up in the hallway but some cruise lines don't like the hallways being blocked...
Hope this helps?!?
Smooth sailing,
